In this description reference will be had to Figs. 2 to 7 inclusive.

,As shown best in Fig.'6,the base-beam 11 is in the form of .a channel and has a vertical wall 20, and upper and lower inwardly extending flanges 21 and 22 whichprovide outer horizontal faces 23. The girt'll, as best il- .lustratedin Fig. 4, includes a channel 25 having anupright web 26 and npper'and lower flanges 27 and 28. I Secured to the web 26 adjacent to the flanges 27 and 28 are channels 29 and secured to theedges of the channels 29remote from the channel 25 is a plate I 30. "The girt 14 therefore consists of a hollow bar ofrectangular cross-section having I external flanges 27 and 28 atthe inner part thereof.

Referring now to Figs. 6 and 7, I Will describe the construction of the means for securing the lower end of each post 15 to the adjacent base-beam 11. In the first place, I

prefer to formeach. post 15 from an I-beam havinga web 32 which extends in a plane at right angles to the plane in'which the adja cent base-beam 11 extends. The lower end of the post 15is notched at 33 so as to provide'a vertical wall 34' which' preferably extends parallel to the. wall 20 and may or may not .Contactthe web; as will'be pointed outlater. The'post's 15-1Il110ll116 inward at their upper ends and it is therefore necessary to provide the notch 33 so that asatisfactory jointmay Fig.6. I *bemade. ig. sis a fragmentaryelevational' view' showing the post construction which supports The angles 35 have legs 36 which engage opposite sides of the Web 32 and are secured thereto by rivets 38. The angles 35also have legs which I are called engaging plates "39, whichextend outward .from theweb 32 in opposite directions and in a planefsubstantially atfright angles thereto. The engaging plates 39 areparallel to the1wall'20 and are vadapted-to be clamped against the wall 20. It is therefore immaterial whether or not the I Qwall 34of the post-l5 engages the wall 20. g In orderto determinethe vertical position of the post l5 '1 'irovidea stop member 4 1,
